    Problems viewing deployed app

    Tommy Powell Newbie

      Hello everyone,

      I am new to JBoss and all appication servers in general. I followed a tutorial and was able to build a .war file for deployment. When i tried to access the deployed page, (or app i am unsure of the correct terminology), I received this exception:

      HTTP Status 500 -

      type Exception report

      message

      description The server encountered an internal error () that prevented it from fulfilling this request.

      exception
